Thanks guys :)



Who knows, maybe in the future I'll desire more but for now the gain vs cost isn't worth it :)

That's with the gopro so there's not much that can be done with that.


Thanks! And no everything is un-modified. As long as we kept the mirror up it was all good! The slow motion was done with a 60d at the maximum frame rate and some adobe software iirc.


Thanks! I'll forward it on to my buddy that edited it, it was our first go so we are more than welcome to feedback!

The 60d was used for all of the slowmotion shots due to the higher frame rate vs. the 5d so we are familiar with its capabilities. Still there is nothing that beats the FF look, especially with my K 50mm F/1.2 ;) To be honest we didn't really desire anything more than we had, so im not sure about more accessories. We didn't need anything more than the cameras, lenses, tripod, and slider :)

Yea living in southern California means there is no lack of open desert space to play in :)


Thanks!


We didn't mod the lenses or camera in any way. My takumar 55mm F/1.8 and 300mm F/4 shot perfectly fine in regular mode, and all of the others shot fine in picture and video mode using liveview. I'll look into the sony though, i've been out of the photo game for a while so im unfamiliar withe the new cameras.


Appreciate it

Canon 5dmkII video w/ pentax glass

Seeing as the prices for used bodies have steadily been dropping, im thinking I may be half jumping ship for the video/FF on the 5dmkII. A good friend of mine bought one recently and we've been testing it with all of my pentax glass and it is near impossible to go back after getting used to that beautiful DOF difference. Anyways we decided to take a shot at making a video of my truck with his "new" camera and my old glass... this was our result.

I must say, the K 50mm F/1.2 SHINES on the canon body. It is like they are meant for eachother I'm ashamed to say :o Are there many other canon FF / Pentax glass users on here?

edit: I forgot to add that some was shot with a gen 1 gopro and some of the slow motion was with a 60d and pentax glass (also worked well).

My good friend picked up a battered 5dmkII for video work, but only had the plastic 50mm to use with it. We searched around a bit, picked up a cheap adapter, and made our first video using my glass and his camera body. The lenses we used were primarily the K 50mm F/1.2, M 85mm F/2, and F 28mm F/2.8. This has pretty much convinced me to pick up a used 5dmkII unless a pentax FF will similar quality video is introduced.

Please go full screen and the maximum resolution you computer can handle to enjoy the video :)

Dont remember, the picture is over a year old. Im sure I was fairly close though... something that you can't really get around with high-magnification macro's.

I dont want to spam the op's thread so if you want more pictures with the lens just check

its a small list of some pictures with the el nikkor I've taken.

looks good Nass, very impressive. Prior to stopping I looked for a 28 religiously but found nothing remotely priced within my range... guess I should have kept looking!
Maybe I'll get back into it when I get a new Imac and we can get some more macro stuff going here :)

I'll chime in. I used to use a shutter speed of 1/40 +/- pretty much exclusively. If your using a flash you dont need any faster, and that way you get some ambient light in the shot as well as flash. Aperture wise when stacking I used to pretty much stick to F/5.6. Sometimes I'd go a little smaller but never past F/8

I've talked to him before, he does both but nothing to deep usually. Definitely not anywhere near the likes of Nikola Rahme or John Hallmen. And you definitely dont need to do either to get stacked images of living bugs. Patience.


going through my flickr my most recent examples (9 months ago and older)


Adult female lynx spider by yeatzee (Officially an adult, but still learning), on Flickr
14 images of a living lynx spider. They sit still all the time if your patient and your approach isn't to obtrusive.


Alien predator by yeatzee (Officially an adult, but still learning), on Flickr

15 of a fly.... hard but possible.


Phidippus Adumbratus by yeatzee (Officially an adult, but still learning), on Flickr


etc.

20 handheld of a jumper. Depending on the species they'll hunker down for a bit every once in a while

Probably the most important thing in macro shooting. And shutter speed is more or less irrelevant with a good flash setup. I often shot at below 1/40 with no issues.


Im not on here often but every once in a while I "hear" my name and check in a bit. The video is pretty old but can be helpful to others i guess. I dont shoot anymore but I still know a decent amount about the field and am willing to answer any specific questions people have.

get out and shoot some animate subjects, or some flowers. A much better way to start learning and practicing as you'll never really get a good shot of bolts no matter the technique.



But what do I know, I dont shoot anymore.

Looks good Nass



"Technical, 3 flashes, 2 from the sides and one from the bottom, el nikkor 50@5.6, 1s exposure through to a smallHD field monitor outputting the background. Tissue paper diffuser moved quite far back, 180 shots stacked in zerene (mainly dmap with a bit of pmax hair action thrown in); fair bit of retouching; further work in CS3 & Topaz detail."

I appreciate the compliment Ben :) Im ashamed to say it, but I havent shot macro's in multiple months :( Im almost never on here as well anymore

reverse stacking is a pretty decent way to get high magnification images, but the results can vary greatly on specific lenses. For example I reversed a 50mm and a 28mm on my sigma 105mm macro many times, resulting in pretty decent results. However ultimately the IQ was just not up to par, especially when compared to other setups. Read this thread, it should answer most of your questions :)

Yes it does a lot! A quick and very old example

7 images stacked at F/5.6

single image @ F/16


Taken at F/16 to demonstrate diffractions effects on sharpness by yeatzee (now 17, but still learning), on Flickr

Magnification was probably in the realm of 3-5:1

Obviously different poses (its a wild animal after all!) but both taken right after eachother and both in focus.

whose bragging? What do I gain by shooting 100 images over 50 if they both accomplish the same goal? Not much to brag about there ;)



I have experience in this technique, and am more than willing to help shed some light :)

It all depends on the situation :) Great answer right?

In all seriousness, 20 images like you said can be more than enough for certain images whereas hundreds can be a necessity for another. The main reason for this is magnification, optics, and diffraction.

Here's an example using a flower as the subject:

At 1:1 diffraction is there, but does not present severe image degradation. Therefore someone might easily get away with less than 10 shots at F/8-16 to say get the entire flower into focus.

But what if you want just the stamen's to fill the frame and be in focus, you'll need to up the magnification. In doing so, you also pronounce diffraction. Assuming you have to bump up the magnification from 1:1 to 5:1, now F/8-F/16 isn't going to get you the best image quality possible because of diffraction. Instead, depending on the lens, F/5.6 or so might be better. So now you've increased the magnification and dropped the Fstop, both of these decisions drastically reduce DOF. So now you must compensate with more images, bringing you from ~10 images to maybe 50+.

Ok so now you want a picture illustrating the detail of the pollen on the Stamen's, and out comes the 10x microscope objective. The thing with objectives is that they have a fixed aperture, usually (dont quote me on this) iirc at around F/2. So now your shooting at 10:1, and with an F-stop of ~F/2. 100 images may not even be enough, maybe even 200. Again it ALL depends.

With all of the above in mind, also note like the above poster said you need a healthy amount of overlay. I always error on the side of caution, and perhaps overlap images more than I need to. Better safe than have hours of work trashed because you wanted to take the easier route :)


edit:


Cotinis Mutabilis by yeatzee (now 17, but still learning), on Flickr

130 image stack, each at F/5.6 for maximum IQ


_IGP0149ejap by yeatzee (now 17, but still learning), on Flickr

single image from the stack.

see why 13 images wouldn't work over 130?

edit 2: maybe Nass, now that he has a stackshot, can take two stacks to better illustrate everything. One with much less photo's using a smaller F/stop, and the other with many more images and a larger F/stop.

Ah gotcha, I didn't know you were comparing it to something like the ebay "focus rails" or whatnot (rrs, novoflex, etc. all basically the same). I was referring to a linear stage which is often specified as a focus rail as well :)
